Why 3DS Isn’t Enough: The Ultimate Security Strategy for Travel Payments

Have you ever felt that despite adding more security layers, fraudsters always find a way in? Many in the industry treat 3DS (Three-Domain Secure) as a definitive solution , but history is repeating itself. Just as we saw with 2DS, 3DS is proving it was never a silver bullet for payment security.

The real issue isn’t a technical glitch in the code; it’s that fraudsters don’t need to break cryptography if they can simply understand and manipulate people.

The “Silver Bullet” Myth: Why 3DS Still Fails

Fraud has evolved far beyond simple bot attacks. Today, criminals use synthetic personas—sophisticated profiles that sound futuristic but are a very present danger. By collecting “beacons” or computer signals, they can replicate more than just your device; they replicate your identity.

Beyond the Device: The Rise of Synthetic Personas

Modern fraud engines struggle because attacks are no longer isolated signals. Fraudsters create a legitimate-looking “behavioral fingerprint” by imitating how a person interacts with a system.

Mimicking the Human Touch

To bypass security, they meticulously replicate:

• Hardware and Browser Settings: Replicating specific configurations and browser behavior.

• Physical Interaction: Mimicking mouse movements and typing speed.

• Precision Data: Even finger pressure and interaction timing are captured.

Once they appear legitimate to the system, they use “silver tongue” social engineering—relying on urgency and authority—to convince users to hand over the final piece of the puzzle, such as an OTP code.

Travel and Airlines: The High-Value Target

Sophisticated fraud is rarely wasted on low-value transactions. Airlines and travel payments sit at the opposite end of the spectrum, making them prime targets.

These transactions are:

• High-value: Justifying the effort and patience of the fraudster.

• Time-sensitive: Creating a sense of urgency.

• Emotionally driven: Making users more susceptible to manipulation.

Changing the Rail: The Power of Alternative Payment Methods (APMs)

If adding more friction to credit cards isn’t the answer, what is? The strategy must shift from defensive fighting to changing the rail. By moving from traditional cards to APMs (Alternative Payment Methods), businesses can eliminate entire attack surfaces by design.

• No Stored Credentials: Sensitive data disappears from the flow.

• Eliminating Replays: Replayable authentication is no longer an option.

• Reduced Disputes: Card scheme disputes and “friendly fraud” lose their leverage.

Conclusion: From Fraud Prevention to Revenue Growth

When you change the payment rail, you stop managing fraud defensively and start building sustainable revenue. International cards only reach about 5% of the market; by embracing local APMs, you can reach everyone. Experts like Paulo Moura and the epag team specialize in these cross-border paths, helping airlines grow with less friction and more security.

FAQ: Frequently Asked Questions

1. Why isn’t 3DS enough to stop travel fraud? Because 3DS focuses on technical signals that fraudsters can now replicate using behavioral mimicry and beacons. It does not account for coordinated human manipulation.

2. How do APMs improve security over traditional cards? APMs remove the need for stored credentials and eliminate replayable authentication, which are two major vulnerabilities in card-based transactions.

3. What makes the travel industry so vulnerable? Travel transactions are high-value and emotionally charged, which justifies the high level of effort and sophistication fraudsters use to bypass security.
